Step By Step Instructions
Fill a saucepan with about one inch of water and bring it to a gentle simmer.
In a heatproof mixing bowl, combine the egg whites, granulated sugar, cream of tartar, and salt.
Place the bowl over the simmering water, making sure the bottom does not touch the water.
Whisk continuously for about four to five minutes until the sugar completely dissolves and the mixture reaches about 160 degrees Fahrenheit.
Remove the bowl from the heat.
Using an electric mixer, beat the mixture on high speed for about seven to ten minutes until stiff, glossy peaks form.
Add the vanilla extract and beat for another thirty seconds.
Use the frosting immediately to decorate cakes, cupcakes, cookies, brownies, or bars.
Variations To Try
Add almond extract instead of vanilla for a different flavor. Mix in lemon or orange zest for a fresh citrus twist. Fold in crushed peppermint candies during the holidays. Lightly toast the finished frosting with a kitchen torch for a roasted marshmallow flavor. Add a few drops of food coloring for themed celebrations.
Freezing Or Restoring
Marshmallow Frosting is best used immediately after preparing.
Store frosted desserts in the refrigerator for up to two days.
Freezing the frosting alone is not recommended because the texture may change after thawing.
Recipe Notes
Make sure all equipment is completely clean and free from grease for the best volume. Separate the egg whites carefully to avoid any yolk. Use the frosting immediately after whipping because it is easiest to spread and pipe while fresh. Avoid humid environments, as moisture can affect the frosting’s stability. A kitchen torch creates a beautiful toasted marshmallow finish.
